===there are more than one artist named "Gestalt" ---1)
Gestalt was formed in 1982 in Lyon. The group draws from the musical Pantheon where Jim Morrisson and Léo Ferré, Hawkwind and Béla Bartok cross, and the most inventive formations of the moment, like Tuxedomoon or Mechanic. In this asserted eclecticism, it is especially its own way which Gestalt seeks. That of a dark energy rock'n'roll interfered research in the compositions.
The full name of DDAA is Déficit Des Années Antérieures.
DDAA was an obscure group of radical experimental noise makers used improvisation and collage to craft strange sounds and deconstructed songs for highly creative music that is as far off the path of conventions as that of similar but more known visionaries like the Residents and Nurse With Wound. In fact, DDAA roughly began the same time as NWW in the late '70s, started by three visual artists, Sylvie Martineau, Jean-Philippe Fee, and Jean-Luc Andre in Lion sur Mer, France.
